If your dog's ears are discharged and smelly, it may be an inflammation or infection, which may be caused by external injury, ear water, bacteria or ear canal parasites. It is recommended that the owner use scissors to trim the hair inside the dog's ears, then use cotton swabs to clean the pus in the ears, and use antibacterial and anti-inflammatory ear drops for treatment.

If there is a dark brown foreign body in the ear canal, and the dog has severe itching and keeps scratching its ears, it may be caused by ear mites. It is recommended to use pet-specific ear mite medicine for treatment after cleaning the foreign body in the ear canal. .
